 ====== Tuning the Z Probe configuration ======
+{{tag>setup articles}}
-Tune your z probe stanza in printer.cfg to improve probe accuracy by decreasing samples_tolerance. Its default is 0.100mm meaning you’re accepting probe results that are off by hundreds of microns while the probe is precise to 0.00250mm - a value of closer to 0.00500 is much more reasonable and accurate, just also increase samples_tolerance_retries as well to 5 and set the probe count to just 2, we just need close agreement in the readings so we didn’t catch the plate as it was thermally changing. Switch from Median to Average.
+The default parameters from Klipper, as well as the Elegoo distributed settings, allow for a lot of error and inaccuracy from the z probe. We can improve on this in terms of performance and accuracy.
+Tune your z probe stanza in printer.cfg to improve probe accuracy by decreasing samples_tolerance. Its Klipper default is 0.100mm meaning you’re accepting probe results that are off by hundreds of microns while the probe is precise with readings below 0.00250mm, so using a value of closer to 0.00333 - 0.00750 is much more reasonable and accurate.
+Given a tighter tolerance we can also speed things up by only two (2) probe readings that now will need to more closely agree. So we'll also increase samples_tolerance_retries as well, We just need close agreement in the readings so we didn’t catch the plate as it was thermally changing. Switch from Median to Average as a median for two points isn't sensible and the average will split the simple difference between the two readings if they don't agree exactly.
+This should leave you with a ''[Probe]'' stanza in ''printer,cfg'' that looks something like this:
